Struct libpijul::small_string::SmallStr

pub struct SmallStr { /* fields omitted */ }

A borrowed version of SmallStr.

Implementations

impl SmallStr

pub fn is_empty(&self) -> bool

use libpijul::small_string::*;
let mut s = SmallString::from_str("");
assert!(s.as_small_str().is_empty());
s.push_str("blah");
assert!(!s.as_small_str().is_empty());

pub fn len(&self) -> usize

use libpijul::small_string::*;
let mut s = SmallString::from_str("blah");
assert_eq!(s.as_small_str().len(), "blah".len())

pub fn as_str(&self) -> &str

pub fn as_bytes(&self) -> &[u8]

pub fn to_owned(&self) -> SmallString

Trait Implementations

impl AsMut<SmallStr> for SmallString

fn as_mut(&mut self) -> &mut SmallStr

Performs the conversion.

impl AsRef<SmallStr> for SmallString

fn as_ref(&self) -> &SmallStr

Performs the conversion.

impl Debug for SmallStr

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SmallStr

impl Ord for SmallStr

fn cmp(&self, x: &SmallStr) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<SmallStr> for SmallStr

fn eq(&self, x: &SmallStr) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<SmallStr> for SmallStr

fn partial_cmp(&self, x: &SmallStr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Storable for SmallStr

fn compare<T>(&self, _: &T, x: &Self) -> Ordering

This is required for B trees, not necessarily for other structures. The default implementation panics.

type PageReferences = Empty<u64>

An iterator over the offsets to pages contained in this value. Only values from this crate can generate non-empty iterators, but combined values (like tuples) must chain the iterators returned by method page_offsets.

fn page_references(&self) -> Self::PageReferences

If this value is an offset to another page at offset offset, return Some(offset). Return None else.

impl UnsizedStorable for SmallStr

const ALIGN: usize

fn size(&self) -> usize

If Self::SIZE.is_some(), this must return the same value. The default implementation is Self;:SIZE.unwrap().

unsafe fn write_to_page(&self, p: *mut u8)

Write to a page. Must not overwrite the allocated size, but this isn’t checked (which is why it’s unsafe).

unsafe fn from_raw_ptr<'a, T>(_: &T, p: *const u8) -> &'a Self

unsafe fn onpage_size(p: *const u8) -> usize

Read the size from an on-page entry. If Self::SIZE.is_some() this must be the same value.
